Composite polymeric electrolyte

Abstract

Composite, ternary, polymeric system formed by intimately mixing a polymeric compound, a metal salt, and a ceramic additive acting both as agent promoting the transport features (conductivity and ion mobility) and as stabilizer of the chemical characteristics (compatibility with the electrode materials) of the polymeric electrolyte.

We claim: 
     
       1. A composite ternary polymer electrolyte consisting of polyethylene oxide, lithium perchlorate and a zeolite which are respectively present in a weight ratio of 20:70:10. 
     
     
       2. The electrolyte of claim 1, wherein the zeolite is in the form of particles dispersed in the system to inhibit crystallization of the polyethylene oxide and to permit use thereof at low temperatures.
